About this webinar

Learn to harness the Internet Archive’s free digital library—a treasure trove of digitized family histories, city directories, census and church records—to enrich your genealogy research. Learn how to build complex prompts to build an index of surnames on a 400 page genealogy book from 1898. Learn how to extract a list of migration routes from the same book, organized by surname, then in generation order, and placed in an Excel file. With the help of AI, you can get the most out of Internet Archive.

Key points and insights

This webinar explores how artificial intelligence can amplify genealogical research by pairing two powerful resources: the Internet Archive’s vast, free digital library and modern AI assistants that can read, summarize, organize, and extract data from lengthy historical texts. Rather than treating AI as a shortcut, the session frames it as a practical “grunt work” partner—especially useful for tackling hard-to-navigate genealogy books, handwritten records, and context-heavy local histories that would otherwise require hours of manual review. The result is a workflow that helps researchers move faster while still staying grounded in solid methodology and source awareness.

  • Internet Archive as a genealogy “unlocks the stacks” tool: The presentation highlights archive.org’s genealogy texts, public-domain materials, and Open Library borrowing options, plus smart ways to search (including Boolean operators) and build personal “bookshelves” for frequently used collections. The Wayback Machine also emerges as a surprisingly useful resource for recovering broken links and preserving webpages for long-term reference.

  • Prompting is the difference between frustration and results: A standout segment demonstrates how better prompts drive better outputs—especially when working with long PDFs that may need to be “chunked” into smaller sections. The free tool Prompt Cowboy is introduced as a shortcut for turning vague requests into structured, high-performing prompts that reliably produce summaries, surname lists, timelines, and other research-ready formats.

  • Responsible AI use remains non-negotiable: The webinar repeatedly emphasizes limits and risks—hallucinations, misread handwriting, and confident “guesses” that can mislead research. Best practices include verifying outputs against originals, avoiding uploads that include living people or sensitive information, documenting methodology, and adding transparent disclosures when AI has been used in writing or analysis.

Viewing the full webinar is strongly worthwhile for anyone ready to move from AI-curious to AI-capable in genealogy. The live demonstrations show exactly how to combine Internet Archive materials with tools such as ChatGPT, Gemini, and specialized options like FamilySearch Full-Text search or handwriting-focused solutions—without losing control of accuracy or ethics. To extend the learning beyond the session, the syllabus resources are an essential next step: the handouts and links provide a ready-to-use roadmap for building prompts, selecting tools, and applying these techniques to real research problems.
